1.1 This practice provides information about utilizing human digital modeling in the design and evaluation of exoskeletons. This practice specifies:
1.1.1 Basic terminology, definitions, principles, methods, inputs, and expected outputs of digital human modeling (DHM) methods.
1.1.2 Principles of modeling methods and expected outputs for designing new exoskeletons or for new work processes, or both.
1.1.3 Principles of modeling methods and expected outputs for evaluating existing exoskeleton devices and human-exoskeleton collaborative/teaming tasks.
1.1.4 Recommendations of modeling methods and expected outputs for consumers to estimate the benefit of using exoskeleton products in their domain.
1.2 The practice does not describe all the details about the model establishment and parameter determination. Instead, this practice provides audiences with necessary modeling procedures and precautions, and results in an interpretation specifically for device design or evaluation purposes.
1.3 The values stated in SI units are to be regarded as the standard. The values given in the examples are not precisely validated, are provided for information only, and are not considered standard.
